Headache. Diagnosing subarachnoid hemorrhage: are CT scans enough?

Peter J Hutchinson et al. Nat Rev Neurol. .

Abstract

Subarachnoid hemorrhage is a rare but potentially fatal cause of headache. According to results from a recent study, CT scans enable clinicians to identify patients with subarachnoid hemorrhage, with a high sensitivity. Does CT imaging rule out the need for lumbar puncture in patients who present with headache?
